a) INTRODUCTION TASK

• 1st . I open the toy. I need scissors.• 2nd I prepare the tray and the work area.• 3rd. I look for the instructions book.• 4 th. I analyze the pieces and I pay attention to the images here.• 5th. I read the information and I follow the instructions step by step.• 6th. First I try by myself, but if I need help I ask for help to my mates (group) or to

my teacher.• 7th. When it´s finished I check how it works.• 8th. Eureka! It´s well done.• 9th. We go together to see how to use a bomb water.• 10 th. We collect and we dry our private water pump and I give turn to my mate,

Silvia . You have to introduce the physical principles involved in a water pump funtion.

• 11 th. Now I´m an engineer! Ja, ja, ja • Thank you teacher• Welcome, Miriam.

B) DEVELOPING

1 st. Water pumps are useful to remove fluid and move from one point to another point.

2nd Water pumps, allow water extract and download.

3rd They are one of the oldest inventions of man.

4th Parts we can see and physical principles: The cylinder, the flow (volume of water) and pressure. It´s important the pressure difference.

Now it´s your turn, Ainhoa.

b) Final task

• History:• 1st .Greeks and Romans were the first to propose the basis of

hydropower.

• They have given rise to the first rotation systems designed to carry water. These systems were used to extract water from the aqueducts and let to carry water to the cities.

• At that time they had already discovered the principles of piston pumps, centrifugal pumps and vacuum pumps, but not applied to construct models of water pumps.

• Thank you, mates. Thank you, Nela.

We have work patience, good manners, to learn to control emotion, turns and of course, how to make a water pump. Genial!
